PERIANTH

n. Pe2r'ia-aanth. Lat., perianthium (from wepi, around, and Mas, a flower). Fr., per i an the. Ger., Bliithendecke. The perigone or floral envelopes as a whole, though Linnaeus restricted the term to the calyx. It is now used in description where the corolla and calyx are not readily distinguished or where only one exists. The term is also applied, although probably erroneously, to the perigynium of the Caricecs and the perichaetium of the Hepaticce. [B, 123, 291 (a, 35).] Double p. A p. consisting of both calyx and corolla. [B, 1 (a, 35).] Simple p. A p. consisting of but one envelope, usually the calyx only. [B, 1 (a, 35).] [s. 237]
